Specification of Iietters Patent.

Patented July 16, 1912.

Application led November 5, 1910. Serial No. 590,789.

To all urhcm it may concern:

Be it known that l, JOHN SINNOTT, a citi- Zen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have -invented a new and useful Improvement in Vehicle-Wheels, of

which the following is a full, clear, and.

exact description, reference being had to the accompanying drawings, which form a part of this specification.

The object of the invention is to absorb shocks to the vehicle without the use of pneumatic or other similar tires.

More specilically, the object of the invention is to provide means to permit the rim to move circumferentially relatively to 'the spokes and radially relatively to the hub. This object is effected by means of the construction hereinafter claimed, one preferred embodiment of which is shown in the drawings, in which- Figure 1 is a detailed -side elevation, partly in section, of a part of my improved wheel; Fig. 2 is a sectional view taken longitudinally through a spoke and transversely through a movable shoe and the rim.-

a is the tire. 4

is the rim, made preferably in two sections, as shown in Fig. 2. The two'halves of the rim are shown as secured together by the bolts c, which also extend through shoes or stops d, within the rim. These shoes,1 which are thus held within the rim, are lo;

cated midway between the normal longi-` tudinal center lines of the several spokes.

e is the hub. Extending radially fronr.

the hub are inner spoke members f' each of which is tubular in form and telescopically engages an outer spoke member g. The outer spoke members are also tubular '1n form throughout most ofI that portion of their length that extends outside the rim. @verlying the inner open end of each outer spoke member g is a washer i, and confined between the washer'and the inner end of the corresponding inner spoke-member f is a compression spring e'. The outer reduced end of each outer spoke-member g is solid and extends through a longitudinally extending slot Z formed in the inner wall of the rim b. rlnis slotis of a length substantially exceeding the width of the outer end 7c of the outer lspokenmember.

m is a shoe of circular cross-section having a lo'ose sliding tit within the rim b. The

central part `of the shoe m'is cut away to form a slot for the reception of the reduced end Zr: of the outer spoke-member.

n 1s a pivot pin extending through the reduced end 7c of the outer spoke-member and the cut-away central section of the shoe ne. Each outer end of the sliding shoem 1s centrally recessed to receive one end of a compression spring o, the other end of which abuts against an annular recess formed in the opposing face of the adjacent y fixed shoe d. y y

In practice, the spokes of the wheel ride backward or forward with relation to the rim in a circumferential direction dependent A upon the point of application of force upon the rim, the shoes m each sliding within the rim in a longitudinal direction against the pressure of one or the other of the engagin springs 0. -At the same time, the part 0% the rim to which force is applied moves in-l wardly toward the hub by reason of the slidlng connection between the spoke-members, this relative movement of spring and hub belng against the -pressure of the springs within the spokes. The pivotal connection between the outer spoke-members g and the sliding shoes m is of great Value and Vimportance, inasmuch as it permits the sliding shoes to have a slight degree of motion relative to the outer spoke-members suii cient to prevent binding of the shoes m within the rim, which would otherwise occur. Having now fully described my inven tion, what I claim and desire to protect by Letters Patent is:

.1. A vehicle wheel Acomprising a hub, a rim, two sets of shoes respectively xed and longitudinally movable within the rim, t-he shoes of one set being arranged alternately with respect to the shoes of `the other set,

springs between adjacent xed andfmovable shoes, inner spoke members secured to the hub, and outer spoke members slidable rela- I.

of the' rimand into'the orifice in the corresponding shoe, pins each extending through the oriced part of one of the movable shoes and the reduced end of the corresponding spoke, other shoes'held Within the rim, and

tothe hub, outer spoke-members telescopii cally engaging the inner between the spoke-members, each spoke-members, springs outer spoke-member having a reduced end extending through a slot in the inner wall of the rim into a slot formed in and extending longitudinally of the corres ending movable shoe, and pins each exten g through the oriiiced part of one of` the movable shoes Qopies' ot this patent may be obtained for ive cents each',

. Washington, D. C.

and the reduced end of the corresponding outer spoke-member.

4. A vehicle wheel comprising a rim of circular cross section, shoes of similar cross 25 section slidable longitudinally in the rim,

,having a cut away part and end recesses, other shoes secured within the rim and having end recesses, coil springs between adjacent shoes of the two sets bottomed within said re-` 3o cesses, a hub, and spokes radiating there-I from, each spoke having a reduced outer end extending through a slot in the inner wall of the rim and engaging the cut-away part of the corresponding movable shoe. .4135
